Mineral Sciences

Smithsonian National Museum of Natural History

Scientists in the Department of Mineral Sciences seek to understand the evolution of the Earth and Solar System by studying samples from environments ranging from the mantle to mine drainages, from volcanic arcs to the asteroid belt. The department is home to world-class collections of rocks, minerals, meteorites, and gems, as well as the instruments our scientists use to study these specimens in detail.

Global Volcanism Program

The Global Volcanism Program seeks to document, understand, and disseminate information about global volcanic activity. Its weekly and monthly reports provide scientists with a record of ongoing eruptions they can use to guide research and hazard management related to volcanoes.
